Preface
Since Ubuntu 8.04 (Hardy Heron) the USB aluminium Apple Keyboard has not worked correctly. A change was added to the Ubuntu Linux kernel to make Apple MacBook keyboards gain additional functionality to their limited laptop style keyboard (Ubuntu bug #162083). Unfortunately this code change has some side effects for owners of the full size USB aluminium Apple Keyboard:
- Function keys have media functions as default. The "fn" key must be pressed and held to access the F-key functionality (except F5 and F6, which are inverted in this respect). (Ubuntu bug #201711)
- Two keys are swapped on international (non-US) keyboard with respect to the printing on the keycaps. (Ubuntu bug #214786)
- Num lock key will when pressed render the keyboard seemingly unusable. The keyboard will simulate a numeric keypad on the alphabet keys. Pressing F6 twice will exit this mode. (Ubuntu bug #201887) (This has been fixed)
- Bug filed in the main kernel bugzilla http://bugzilla.kernel.org/show_bug.cgi?id=10818. Please help if you think that the kernel developers are wrong, assuming that the keyboard have to behave like under MacOS.
Default Behavior
This section describe the default behavior of every Apple keyboard.
Apple slim aluminium keyboard (0220)
- 'fn'+'Enter' -> Insert
- 'fn'+'Backspace' -> Delete
- 'fn'+'Up' -> PageUp
- 'fn'+'Down' -> PageDown
- 'fn'+'Left' -> Home
- 'fn'+'Right' -> End
- 'Clear' behave like 'NumLock'
(See #262408 as there is patch submit to map F13, F14 and F15 to PrintScreen, ScrollLock and Pause.)
Corrections
Change Function Key behavior
This section of the document describe how to change the behavior of 'fn' key to better match what user expect. (See #201711, #162083) Here a description of each behavior :
- 0 = disabled : Disable the 'fn' key. Pressing 'fn'+'F8' will behave like you only press 'F8'
- 1 = fkeyslast : Function keys are used as last key. Pressing 'F8' key will act as a special key. Pressing 'fn'+'F8' will behave like a F8.
- 2 = fkeysfirst : Function keys are used as first key. Pressing 'F8' key will behave like a F8. Pressing 'fn'+'F8' will act as special key (play/pause).
Ubuntu 9.04 (Jaunty Jakalope)
Temporarily
This section describe how to change the behavior of 'fn' with immediate effect (Restarting will reset the configuration). Execute the following commands to change the fnmode parameters. See section above for a description of available value.
$ sudo bash # echo 2 > /sys/module/hid_apple/parameters/fnmode # exit
Permanently
This section describe how to change the behavior of 'fn' permanently. There is many way to proceed with this modification. Each sub section describe one way to permanently change the configuration.
With .conf file (Recommended)
1. Edit or create the file /etc/modprobe.d/hid_apple.conf, e.g.:
sudo gedit /etc/modprobe.d/hid_apple.conf
2. Add this line to the previously open file.
options hid_apple fnmode=2
3. Save the file and execute the following command to notify hid_apple module to reload it's configuration.
sudo update-initramfs -u
4. Reboot
With rc.local
1. Edit the /etc/rc.local file.
sudo gedit /etc/rc.local
2. Add this line near the end of the file, before the "exit" line:
echo 2 > /sys/module/hid_apple/parameters/fnmode
3. Reboot
With sysfs.conf
1. Edit the /etc/sysfs.conf file.
sudo gedit /etc/sysfs.conf
2. Add this lines to the end of the file.
module/hid_apple/parameters/fnmode = 2
3. Reboot
Ubuntu 8.10 (Intrepid Ibex)
Temporarily
With immediate effect, try
sudo bash echo 2 > /sys/module/hid/parameters/pb_fnmode exit
Permanently
1. Edit the file /etc/modprobe.d/options, e.g.:
sudo gedit /etc/modprobe.d/options
2. Add the line:
options hid pb_fnmode=2
3. Save the file and execute the following command:
sudo update-initramfs -u
4. Reboot
Alternatively, you can modify /etc/rc.local to similar effect.
- Edit the /etc/rc.local file:
sudo gedit /etc/rc.local
- Add this line to the end of the file:
echo 2 > /sys/module/hid/parameters/pb_fnmode
Alternatively, you can modify /etc/sysfs.conf to similar effect.
- Edit the /etc/sysfs.conf file:
sudo gedit /etc/sysfs.conf
- Add this lines to the end of the file:
module/hid/parameters/pb_fnmode = 2
Correcting the two swapped keys for international (non-US) keyboards
This section describe how to fix the issue related to the swapped key when using international keyboard. (See #214786)
Ubuntu 9.04 (Jaunty Jakalope)
Need to confirm if the problem persist as there is modification done in the kernel to fix the problem.
Ubuntu 8.10 (Intrepid Ibex)
1. Open the 'System->Preferences->Keyboard' dialog 2. Choose the 'Layouts' tab 3. Press 'Layout Options...' 4. Navigate to 'Miscellaneous compatibility options' 5. Enable the option: Swap keycodes of two keys when Mac keyboards are misdetected by kernel.
Mapping keys (Insert, Alt, Cmd, etc.)
This section describe how to change the mapping of key to better match PC's keyboard. e.g.: Swap the Alt key and Command key. The idea is to make the keyboard work more like a normal PC keyboard.
Ubuntu 9.04 (Jaunty Jakalope)
Since Xmodmap have been replace by X Keyboard Extension, it's impossible to use Xmodmap to proceed with the mapping. Configuration can be done using the Keyboard preference tool.
Ubuntu 8.10 (Intrepid Ibex)
! Configure F13 as Insert key, F14 as PrintScr, F15 as ScrollLock ! and F16 as Pause/Break. keycode 191 = Insert keycode 192 = Print Sys_Req keycode 193 = Scroll_Lock keycode 194 = Pause Break keycode 195 = XF86AudioMute keycode 196 = XF86AudioPrev keycode 197 = XF86AudioNext !

2. Load the configuration by executing a command similar to the following.
xmodmap ~/.Xmodmap
Note : The configuration should be load on next logon.
Ubuntu 8.04 (Hardy Heron)
This section describe how to change the mapping for Ubuntu 8.04 (Hardy Heron) with kernel >= 2.6.27. 1. Edit or create ~/.Xmodmap file with a content similar to the following.
! Configure F13 as Insert key ! F14 as PrintScr | F15 as ScrollLock ! F16 as Pause/Break keycode 182 = Insert keycode 183 = Print Sys_Req keycode 184 = Scroll_Lock keycode 93 = Pause Break !

Configure '=' key on numpad as '='. keycode 0x9D = equal
2. Load the configuration by executing a command similar to the following.
xmodmap ~/.Xmodmap
Note : The configuration should be load on next logon.
